From 0dbfafa5fcd4dd189e2adc7b6ed9e0405e846d79 Mon Sep 17 00:00:00 2001 From: Alexander van Heukelum Date: Wed, 23 Apr 2008 15:09:05 +0200 Subject: x86: move i386 memory setup code to e820_32.c The x86_64 code has centralized the memory setup code in e820_64.c. This patch copies that approach to i386: - early_param("mem", ...) parsing is moved from setup_32.c to e820_32.c. - setup_memory_map() and finish_e820_parsing() are factored out from setup_arch(), and declarations are added to e820_32.h. - print_memory_map() is made static and removed from e820_32.h. - user_defined_memmap is marked as __initdata.
